Phyllanthus discoides

This alkaloid (C13H1503N mp 169-170° [a]D —450°) was first obtained from Phyllanthus discoides Muell. Arg. (134) and presently from Securinega suffruticosa Rehd. Its structure (146) was mooted on the basis of a spectral study and confirmed when it was obtained in excellent yield by the hydrogen peroxide oxidation of allosecurinine (147) (135). [Pg.293]

Virosecurinine and viroallosecurinine obtained from the leaves of Securinega virosa were found to be the enantiomers of securine and allosecurinine, respectively. Securinega alkaloids obtained from the roots of Phyllanthus discoides are securinine, allosecurinine, and phyllantine. These alkaloids are biogenetically produced from lysine and a C6-C3 unit derived from tyrosine (Fig. 5.2.6). [Pg.208]
